The present patent refers to a process for the recycling and recovery of waste, particularly that of plastified and aluminized packaging, cartoned or not, by means of a method and equipment for extracting and separating the main components present in them for the recovery of waste, avoiding environmental pollution, recycling of waste constituents, and recovery of constituents: Plastic, aluminum and paper in their original form, with the steps A, B, C, D, E, F, G, H, I, J, L, M, O, P, Q e R, bringing advantages of obtaining reusable grade polymer; obtaining isolated aluminum; to make use of a low cost and low energy consuming solvent; to allow the pulp cellulose to be recycled in the production of paperboard for boxes, to be incorporated as part of a mechanical pulp load or even to be incorporated to the bleaching process; to have lower processing and investment costs and to have a lower cost/benefit ratio.

A pellet composed of a polymeric blend having a polyolefin and polylactic acid.

Provided is A polypropylene-based resin composition comprising 2 mass % to 30 mass % of a polypropylene resin (X1) having specific properties, 5 mass % to 98 mass % of a polypropylene resin (X2) having specific properties, and 0 mass % to 80 mass % of a polypropylene-based resin (Y) having specific properties, wherein the total amount of the polypropylene resin (X1), the polypropylene resin (X2) and the polypropylene-based resin (Y) is 100 mass %.

A method of recycling a plastic includes decomposing the plastic in the presence of a catalyst to form hydrocarbons. The catalyst includes a porous support having an exterior surface and defining at least one pore therein. The catalyst also includes a depolymerization catalyst component disposed on the exterior surface of the porous support for depolymerizing the plastic. The depolymerization catalyst component includes a Ziegler-Natta catalyst, a Group IIA oxide catalyst, or a combination thereof. The catalyst further includes a reducing catalyst component disposed in the at least one pore.

A biaxially stretched polypropylene film for capacitors which has protrusions on both sides and has a thickness (t1[μm]) of 1 μm to 3 μm, wherein Formulae (1) to (4) are satisfied by an A-side as one film surface and a B-side as another film surface:
|Pa−Pb|≧200;  (1)
0.350≦Pa/SRzA≦0.700;  (2)
500 nm≦SRzA≦1,200 nm;  (3)
50 nm≦SRzB≦500 nm;  (4)
wherein, in Formulae (1) to (4), Pa is a number per 0.1 mm.sup.2 of protrusions on the A-side, Pb is a number per 0.1 mm.sup.2 of protrusions on the B-side, SRzA is a ten-point average roughness of the A-side, and SRzB is a ten-point average roughness of the B-side.

The present disclosure provides polypropylene compositions that have a high gloss and minimum or no haze while also having a high melt strength (e.g., high temperature resistance) and a relative high stiffness. Polypropylene compositions contain one or more base polypropylenes (e.g., trimmed polypropylenes (tPPs)) and one or more clarifying agents. The base or trimmed polypropylene contains at least 50 mol % of propylene and has a molecular weight distribution (Mw/Mn) in a range from 7 to 22, a z-average molecular weight of less than 2,500,000 g/mol, a branching index (g′.sub.vis) of at least 0.95, and a melt strength of less than 20 cN determined using an extensional rheometer at 190° C. The base or trimmed polypropylene can be produced from one or more high melt strength polypropylenes (HMS PPs).

Low basis weight films having a heat capacity×density value of greater than about 970,000 Ws/m.sup.3K, as measured by the method described herein, the films having a basis weight of less than about 16 gsm and comprising at least about 10% polypropylene.

The present invention relates to active and intelligent additives having hybrid characteristics, that are compatible with polymers, are thermally and mechanically stable, are capable of releasing electrons and/or photons in the presence of chemical compounds, specifically amino compounds, amide compounds, oxygen reducing compounds, water or vapors thereof. The active and intelligent additives incorporate themselves into polymer matrices allowing the obtainment of active and intelligent polymeric articles. These active and intelligent polymeric articles may act as inhibitors of growth of microorganisms and fungi, as well as indicators of the presence of gasses, either in the atmosphere or caused by the decomposition of foodstuffs, for example.

The present disclosure provides a thin film including a first thermoplastic polyolefin (TPO) elastomer which is anhydride-grafted. The present disclosure further provides a method for manufacturing the thin film, a laminated material and a method for adhesion.

The present invention provides a propylene-based resin microporous film which has excellent electrolyte solution retention property, and can provide a lithium ion battery in which a decrease in discharge capacity is highly reduced even after repeated charge and discharge. The propylene-based resin microporous film is a propylene-based resin microporous film having micropores, wherein a propylene-based resin having a weight average molecular weight of 250,000 to 500,000, a melting point of 160 to 170° C., and a pentad fraction of 96% or more is contained, the surface aperture ratio is 27 to 42%, the ratio of a surface aperture ratio to a porosity is 0.6 or less, and the degree of gas permeability is 50 to 400 s/100 mL.
